This electrical equipment grounding device increases the flexibility between the electrical equipment and the grounding device, replaces the original fixed welding, and enables the electrical equipment and the grounding device to be movable and rotatable. The extrusion screw is rotated to drive the extrusion plate to clamp the grounding wire on the electrical equipment, and then the extrusion screw is rotated to drive the extrusion plate to move, and the grounding wire on the electrical equipment is clamped for the second time. The connection steps between the grounding wire of the electrical equipment and the grounding device are simple and quick, so that the connection form between the electrical equipment and the grounding device is flexible and can be freely disassembled.

[0004] At present, in the process of drilling the grounding pole deep into the ground, if a gravel layer is encountered, it is necessary to manually dig out the gravel or move the device to another place to continue the grounding operation. The process is cumbersome and inconvenient; in addition, after drilling through the gravel layer, some gravel will be cut and the edges will become sharper. At this time, if the grounding pole is scratched when passing through these drilled gravel, it will cause serious scratches on the grounding pole, causing damage, affecting the normal use of the grounding pole; and in the process of the grounding pole going deep into the ground, due to the lack of support for the surrounding soil layer, such as some soft sand, it is inevitable that the surrounding soil layer will flow back and contact the grounding pole again. In order to prevent the grounding pole from being scratched or bitten by small animals in the soil layer, causing damage, the grounding pole needs to be protected.

[0020] The present invention is further described below in conjunction with specific embodiments.

[0021] In order to solve the problem that when the grounding column 26 is deeply buried underground, if a gravel layer is encountered, it is necessary to manually dig out the gravel or move the device to another place to continue the grounding operation, which is a cumbersome and inconvenient process. Figure 1 - Figure 7 As shown: A grounding device for electrical equipment in a power plant comprises a base 1, wherein a plurality of fixed plugs 11 are symmetrically fixedly connected to the bottom end of the base 1, and the device is stabilized by the plurality of fixed plugs 11, and a cable fixing seat 12 is fixedly connected to the top end of the base 1. When in use, the grounding wire of the electrical equipment is fixedly connected to the cable fixing seat 12, so that the grounding wire of the electrical equipment is connected to the grounding device, and then, according to the specific use of the electrical equipment, the grounding column 26 is extended into the ground to a required depth for grounding and conducting operations, and a grounding component 2 is installed through the base 1. By setting the grounding component 2, when performing the grounding operation, a motor 25 is started, wherein the motor 25 is a forward and reverse motor and is detachable, and the forward rotation of the motor 25 drives the threaded rod 24 and the grounding column 26 to rotate. The threaded sleeve 21 passing through and fixed on the base 1 is used to cooperate with the threaded sleeve 21 and the threaded rod 24, so that the motor 25, the support plate 23, the threaded rod 24 and the grounding column 26 go deep into the ground. If a gravel layer is encountered, the output power of the motor 25 is increased, and the rotation speed of the threaded rod 24, the grounding column 26 and the spiral drill bit 27 is increased, and the gravel layer is drilled with the spiral drill bit 27 to continue to go deeper. Before the grounding operation is carried out, an address survey will be carried out, and the grounding operation will not be carried out in a place where the gravel thickness is too thick. Compared with the traditional grounding device, when facing the gravel layer, the gravel needs to be cleaned out, or a place with less gravel needs to be selected. The device improves the applicability of the soil layer, reduces labor, and improves the practicality of the device.

[0022] A grinding assembly 3 is slidably installed on the side wall of the grounding assembly 2. By setting the grinding assembly 3, when drilling through the gravel layer, the electromagnet 31 is energized. After the electromagnet 31 is energized, a magnetic pole is generated at the end thereof, wherein the magnetism of the adjacent ends of the electromagnet 31 and the permanent magnet 37 is opposite. The magnetic attraction force generated by the opposite magnetic poles drives the grinding disc 35 to move upward along the grounding column 26, wherein the amount of electricity energized is sufficient to make the magnetic attraction between the electromagnet 31 and the permanent magnet 37 greater than the weight of the grinding disc 35. During the rising process of the grinding wheel 35, the multiple limit holes 38 opened on the inner wall of the grinding wheel 35 cooperate with the limit blocks 34 on the side walls of the grounding column 26, so that the limit blocks 34 and the limit holes 38 are snap-fitted together, and at this time they are in contact with the push plate 33 and compress the second spring 32, and the grinding wheel 35 is driven to rotate synchronously through the snap-fitting, so as to grind the surrounding sharp gravel to make it blunt, avoid scratching the grounding column 26, causing damage to the grounding column 26, and affecting the grounding effect of the grounding column 26.

[0023] A protection component 4 is fixedly installed on the top of the base 1. By setting the protection component 4, during the rotation of the threaded rod 24, the first synchronous wheel 43 is driven to rotate synchronously, and the second synchronous wheel 45 is driven to rotate by the synchronous belt 46, so that the reciprocating screw 44 is rotated synchronously. The reciprocating screw 44 rotates to drive the sliding sleeve 47 and the piston plate 416 to reciprocate up and down in the vertical direction, so that the gas in the gas storage tank 42 that can improve the conductive effect is introduced into the telescopic tube 41. The airflow generated when the gas that can improve the conductive effect is introduced into the telescopic tube 41 and the conductive gas is continuously The air inside the telescopic tube 41 is discharged through the exhaust pipe 414, and a second one-way exhaust valve 415 is provided inside the exhaust pipe 414, so that the airflow inside the telescopic tube 41 can only be discharged along the exhaust pipe 414. By continuously injecting gas that can improve the conductive effect into the telescopic tube 41, the original air inside the telescopic tube 41 is completely exhausted and replaced, so that the space between the telescopic tube 41 and the grounding column 26 is filled with gas that can improve the conductive effect. When the grounding column 26 is grounded and conductive, it contacts the soil layer through the conductive gas and the external iron telescopic tube 41 to perform the grounding operation.

[0024] The grounding component 2 includes a threaded sleeve 21, which is fixedly connected to the base 1 through a threaded sleeve 21, a sliding rod 22 is symmetrically fixedly connected to the top of the base 1, and a plurality of sliding rods 22 are commonly connected to a support plate 23 through a sliding connection, a motor 25 is fixedly connected to the top of the support plate 23, a threaded rod 24 is fixedly connected to the output end of the motor 25, and a side wall of the threaded rod 24 is threadedly connected to the threaded sleeve 21 through a threaded connection. When the motor 25 is working, the threaded rod 24 and the grounding column 26 are driven to move downward, and this process will drive the motor 25 and the support plate 23 to move downward synchronously.

[0025] One end of the threaded rod 24 away from the motor 25 is fixedly connected to a grounding column 26, the bottom end of the grounding column 26 is fixedly connected to a spiral drill bit 27, the side wall of the grounding column 26 is fixedly connected to a mounting column 28, a cavity 29 is opened inside the mounting column 28, the side wall of the grounding column 26 is fixedly connected to a thorn gear 210, the thorn gear 210 is located inside the cavity 29, and a slider 211 is slidably connected inside the slot of the thorn gear 210, and each slider 211 is a semi-cylindrical structure.

[0026] The side wall of the slider 211 is symmetrically fixedly connected with connecting rods 212, one end of each connecting rod 212 penetrates the inner wall of the cavity 29 and extends to the outside of the mounting column 28, the two connecting rods 212 are commonly fixedly connected with a top plate 214, and the multiple top plates 214 are commonly fixedly connected with a stretching membrane 215, the side wall of the slider 211 is symmetrically fixedly connected with first springs 213, one end of each first spring 213 is fixedly connected to the inner wall of the cavity 29, and each first spring 213 is sleeved on the outer wall of the adjacent connecting rod 212.

[0027] In this scheme: when the grounding operation is performed, the motor 25 is started, wherein the motor 25 is a forward and reverse motor and is detachable, and the threaded rod 24 and the grounding column 26 are driven to rotate by the forward rotation of the motor 25, and the threaded sleeve 21 that penetrates and is fixed to the base 1 is used, and the threaded sleeve 21 cooperates with the threaded rod 24, so that the motor 25, the support plate 23, the threaded rod 24 and the grounding column 26 go deep into the ground. If a gravel layer is encountered, the output power of the motor 25 is increased, and the speed of the threaded rod 24, the grounding column 26 and the spiral drill bit 27 is increased, and the gravel layer is drilled with the spiral drill bit 27 to continue to go deep. Before the grounding operation is performed, a geological survey will be carried out, and the grounding operation will not be performed in a place where the gravel thickness is too thick. Compared with the traditional grounding device, when facing the gravel layer, the gravel needs to be cleaned out, or a place with less gravel is selected. The device improves the applicability of the soil layer, reduces labor, and improves the practicality of the device; As the grounding column 26 goes deeper, the thorn gear 210 rotates synchronously with the grounding column 26. As the thorn gear 210 rotates in the forward direction, the slider 211 in each slot is pushed to move outward. Each slider 211 drives the adjacent top plate 214 to move outward synchronously through the connecting rod 212, so that the diameter of the stretching film 215 increases. As the thorn gear 210 continues to rotate, the slider 211 will be pushed to move to the inside of the next slot under the elastic action of the first spring 213. At this time, the diameter of the stretching film 215 decreases, and the cycle repeats, thereby continuously expanding outward to contact the soil layer around the grounding column 26, and the surrounding soil layer is compressed. Push outward, so that sharp objects in the soil layer around the grounding column 26 are kept away from the grounding column 26, so as to prevent the grounding column 26 from being scratched by sharp objects and affecting the conductor properties of the grounding column 26, thereby improving the protection of the grounding column 26; wherein the stretch film 215 is made of scratch-resistant material and is retractable. In addition, during the rotation of the thorn gear 210, when the slider 211 moves to the end of the slot of the thorn gear 210, the diameter of the cavity 29 is larger than the thorn gear 210 and the slider 211, so as not to limit the slider 211 and affect the movement of the slider 211, and during the expansion process, the maximum diameter of the stretch film 215 stretched is slightly larger than the diameter of the spiral drill bit 27.

[0028] In order to solve the problem that after drilling through the gravel layer, some gravel pieces will be cut and their edges will become sharp. At this time, if the grounding post 26 is scratched when passing through these drilled gravel, it will cause serious scratches on the grounding post 26, causing damage and affecting the normal use of the grounding post 26. Figure 4 - Figure 5 and Figure 6 and Figure 8 As shown: The grinding assembly 3 includes an electromagnet 31, which is fixedly connected to the bottom wall of the mounting column 28. A plurality of second springs 32 are symmetrically fixedly connected to the bottom end of the mounting column 28. A push plate 33 is fixedly connected to the plurality of second springs 32. A plurality of limit blocks 34 are fixedly connected to the side wall of the mounting column 28 at equal angles.

[0029] The bottom end of each limit block 34 is a wedge-shaped structure, and a tray 36 is fixedly connected to the side wall of one end of the mounting column 28. A grinding disc 35 is slidably connected to the side wall of the mounting column 28. A plurality of limit holes 38 are provided on the inner wall of the grinding disc 35. The top of each limit hole 38 is a wedge-shaped structure, and a permanent magnet 37 is fixedly connected to the top of the grinding disc 35.

[0030] In this scheme, when drilling through the gravel layer, the electromagnet 31 is energized, and magnetic poles are generated at the ends of the electromagnet 31 after being energized, wherein the magnetism of the adjacent ends of the electromagnet 31 and the permanent magnet 37 is opposite, and the magnetic attraction force generated by the opposite magnetic poles drives the grinding disc 35 to move upward along the grounding column 26, wherein the amount of power supplied is sufficient to make the magnetic attraction force between the electromagnet 31 and the permanent magnet 37 greater than the weight of the grinding disc 35, and during the rising process of the grinding disc 35, a plurality of limit holes 38 opened on the inner wall of the grinding disc 35 are used to contact the limit blocks 34 on the side walls of the grounding column 26. The cooperation between the limit block 34 and the limit hole 38 makes the limit block 34 engage with the limit hole 38, and at this time contacts the push plate 33 and compresses the second spring 32, and drives the grinding disc 35 to rotate synchronously after the engagement, grinds the surrounding sharp gravel to make it blunt, avoids scratching the grounding column 26, causes damage to the grounding column 26, and affects the grounding effect of the grounding column 26, wherein the bottom of the limit block 34 and the top of the limit hole 38 are both wedge-shaped structures, so that when the grinding disc 35 moves up, the wedge-shaped structure is used to make it easier for the grinding disc 35 to engage with the limit block 34; When passing through the gravel layer, the electromagnet 31 can be powered off. After the electromagnet 31 is powered off, it loses its magnetism. Under the elastic action of the second spring 32, the push plate 33 is driven to move downward and reset, thereby pushing the grinding disc 35 to leave the limit block 34, releasing the clamping of the grinding disc 35, and stopping it from continuing to grind. By controlling the use of the grinding disc 35, the grinding disc 35 is prevented from rotating synchronously all the time, and the use load of the motor 25 is reduced. The diameter of the grinding disc 35 is slightly larger than the diameter of the spiral drill bit 27, so as to avoid that the diameter is too large to affect the penetration into the ground, and too small to be insufficient for grinding sharp gravel.

[0031] In order to solve the problem that when the grounding pole 26 is deeply buried underground, due to the lack of support for the surrounding soil layer, for example, some soft sandy soil, the surrounding soil layer will inevitably flow back and contact the grounding pole 26 again. In order to prevent the grounding pole 26 from being scratched or bitten by small animals in the soil layer, causing damage, the grounding pole 26 needs to be protected, such as Fig. 9 - Fig.10 As shown: The protective component 4 includes a telescopic tube 41, one end of the telescopic tube 41 is fixedly connected to the bottom wall of the base 1, and the other end of the telescopic tube 41 is fixedly connected to the top wall of the mounting column 28. The side wall of one end of the threaded rod 24 close to the motor 25 is fixedly connected to a first synchronous wheel 43, and a reciprocating screw 44 is rotatably connected to the support plate 23, and a second synchronous wheel 45 is fixedly connected to the side wall of one end of the reciprocating screw 44.

[0032] The first synchronous wheel 43 and the second synchronous wheel 45 are connected by a synchronous belt 46, the top of the base 1 is fixedly connected to the air storage tank 42, the top of the support plate 23 is symmetrically fixedly connected to the support block 417, the multiple support blocks 417 are commonly fixedly connected to the sealing box 418, the side wall of the reciprocating screw 44 is threadedly connected to the sliding sleeve 47, and the top of the sliding sleeve 47 is symmetrically fixedly connected to the fixing rod 48.

[0033] The two fixing rods 48 are commonly fixedly connected with a piston plate 416, and the piston plate 416 is sealingly and slidably connected to the inner wall of the sealing box 418. An air intake pipe 49 is fixedly connected to the side wall of one side of the sealing box 418. One end of the air intake pipe 49 is fixedly connected to the top of the air storage tank 42. A one-way air intake valve 410 is installed inside the air intake pipe 49. A connecting pipe 412 is fixedly connected to the side wall of the other side of the sealing box 418.

[0034] One end of the connecting pipe 412 passes through the side wall of the base 1 and is fixedly connected to the telescopic pipe 41. The side wall of the telescopic pipe 41 is fixedly connected with a first one-way exhaust valve 413. One end of the exhaust pipe 414 passes through and is fixedly connected to the base 1. A second one-way exhaust valve 415 is installed inside the exhaust pipe 414.

[0035] In this solution, as the grounding column 26 continues to go deeper into the ground, the telescopic tube 41 will be driven to gradually expand, wherein the telescopic tube 41 is a corrugated tube structure, which can be folded and expanded, and the telescopic tube 41 is made of iron material, which has good protection and conductivity, so that the soil contacts the telescopic tube 41 after backflow, and the grounding column 26 is protected; because there is a certain gap between the telescopic tube 41 and the grounding column 26, the conductive effect of the grounding column 26 will be affected, so that during the rotation of the threaded rod 24, the first synchronous wheel 43 is driven to rotate synchronously, and the second synchronous wheel 45 is driven to rotate by the synchronous belt 46, Thus, the reciprocating screw 44 is made to rotate synchronously. By controlling the diameters of the first synchronous wheel 43 and the second synchronous wheel 45, the speed of the reciprocating screw 44 is made appropriate to avoid the reciprocating screw 44 rotating too fast and breaking. The reciprocating screw 44 rotates to drive the sliding sleeve 47 and the piston plate 416 to reciprocate up and down in the vertical direction. When the piston plate 416 moves downward, the pressure difference generated by the sealed sliding between the piston plate 416 and the inner wall of the sealing box 418 is utilized, and the one-way air intake valve 410 inside the air intake pipe 49 is cooperated, so that the gas in the air storage tank 42 can improve the conductive effect. The gas that can improve the conductivity in the sealing box 418 can only enter the interior of the telescopic tube 41 along the air inlet pipe 49. When the piston plate 416 moves upward, the pressure inside the sealing box 418 increases, and cooperates with the first one-way exhaust valve 413 in the connecting pipe 412, so that the gas that can improve the conductivity in the sealing box 418 can only enter the interior of the telescopic tube 41 along the connecting pipe 412. The airflow generated when the gas that can improve the conductivity is introduced into the interior of the telescopic tube 41 and the conductive gas continuously enters the interior of the telescopic tube 41, the air inside the telescopic tube 41 is discharged through the exhaust pipe 414, and the exhaust pipe 414 is provided with a second one-way exhaust valve. Valve 415 allows the air flow inside the telescopic tube 41 to be discharged only along the exhaust pipe 414. By continuously injecting gas that can improve the conductive effect into the telescopic tube 41, all the original air inside the telescopic tube 41 is exhausted and replaced until the grounding column 26 moves to a suitable depth. Then, the second one-way exhaust valve 415 and the first one-way exhaust valve 413 are closed, so that the space between the telescopic tube 41 and the grounding column 26 is filled with gas that can improve the conductive effect. When the grounding column 26 is grounded and conductive, it contacts the soil layer through the conductive gas and the external iron telescopic tube 41 to perform the grounding operation.
